"She at no point either admits or implies (to detectives) that she killed Shakespeare or had any part in helping anyone to do so," Hileman told jurors.

Hileman went on to say Moore didn't come forward to report the crime for one simple reason: she was afraid.

"She has not freely shared with them, because her life and the life of her son have been threatened by the people responsible and she's frightened."

But the prosecution says the claim is just another lie Moore has told to cover-up her role in the fatal shooting.

Shakespeare, who won a $30-million lottery jackpot in 2006, was found buried under a concrete slab in the backyard of a home owned by Moore. Officials say Moore took control of all of Shakespeare's finances before ultimately killing the 43-year-old.

"She buried him on her property and she took extreme calculated steps to avoid detections, apprehension and the truth," Assistant State Attorney Jay Pruner said during opening statements.
